| No, the most you can try to do is try to control it by applying some fungicides and maintaing good cleaning practices. The Alabama Cooperative Extension Service (ACES) says "The fungus Glomerella cingulata causes camellia dieback. Symptoms are the sudden wilting of a twig of new growth or the development of cankers on a limb or trunk. Control by cutting off infected, wilted areas down to clean, uninvaded wood. Infected wood is brown with an orange cast. Sterilize the pruners with isopropyl alcohol between cuts. Dieback is spread when contaminated water splashes on new growth or a plant wound, such as a fresh leaf scar. C. sasanqua is more susceptible to dieback than is C. japonica. It is more prevalent in humid areas. Spray thiophanate-methyl at labeled rates every 2 or 3 weeks beginning in early spring and continue fungicide applications into June." |
